Exposed a "total linked records" field for epics and features

We are interested in identifying the number of dependencies a particular epic or feature has to proactively manage the sequencing work and identify potential schedule risk. Our teams prefer roadmaps to visualize the work. However, custom roadmaps do not show dependency links. Another way to visual dependency risk would be to create a heat map by color coding epics or features based on the number of records that are linked to them. Exposing a "total link records" would allow us to create the custom roadmap "heat map".
